'I'he member 6 terminates at its lower end in a substantially rectangular base as shown. The member 6 is of such size and so positioned upon the member I5 that it leaves the shoulders I6 on the member I5 and extends beyondA the inner walls 20 of the cutout portion I1 over the entire distance between the tension posts I2 as is clearly shown in the drawing. Conversely stated the cutout portion I1 must be so formed that its inner wall 20 will fall within the ends I9 of the member 6 for the entire distance between the tension posts I2. 'I'his structure has the double effect of lessening the weight of the ensemble and insuring that the thread T will not contact with any portion of the carrier Cv except the glazed member 6.

The carrier C is so proportioned that when inserted in its position in the pocket P a substantial portion of the element 6 will be above the wall 2 of the pocket P as is clearly shown in Figures 2 and 3. In its preferred position when in use the thread guide rests upon and is supported by the :door 22 of the tension box P. In Figures 2 and 3 the lower end 2| of the thread guide is shown r as somewhat above the floor 22 of the tension box and the clearance between the walls of the tension box and the walls of the thread guide have been exaggerated for the purpose of greater clearness of illustration. The actual condition of the element C when in use is to be considered as that shown for the element D in Figure 6, wherein the clearance between the side walls 48 of the member D andthe walls 49 of the pocket P has been exaggerated for the purpose of clearness.

Although the manner of using my improved device is believed to be obvious from the foregoing description yet to obviate any possibility of a misunderstanding the following detailed description is here given:

We start with the ensemble such as shown in Figure 4 with the thread carrier C outside of its pocket and having the spring 9 positioned in the spring receiving bore 8. The ensemble is now inserted into the pocket P in such a manner that its lower end 2| rests upon the floor 22 of the pocket P. The spring 9 is of such construction that when not under tension its length is less than the distance between the downwardly converging walls 3 of the pocket P at the upper end of the pocket but more than the distance between these walls at the point where the spring contacts with them when the thread carrier is in theoperative position shown in Figures 2 and 3. Because of this structure the walls 3 serve as cams and serve to place the spring l9 under compression as the carrier C is-inserted in place. The thread T coming from the bobbin is now strung so that it runs over the surface of the carrier 6 in the position shown by the full lines in Figure Y1. If greater tension is desired the thread T is positioned to take the course T1 (shown by the dot and dash lines in Figure 1) wherein it winds around a single tension post I2. If still greater tension is desired the thread T is positioned to take the course T2 (shown by the double-dot and dash lines in Figurev 1) wherein the threads wind around both tension posts I2 on their way to the SIlaDDeTS The thread carrier D differs from the carrier C in the following particulars:

(l) The body member 25 having the spring receivingbore 26V formed therein has been substi? tuted for the body member tions 5, 'I and I5.

consisting of the por- (2) The thread bearing member 21 has been substituted for the thread bearing member 6.

(3) The tension ridge 29 has been substituted for the tension posts I2.

The tension ridge 29 has the thread guiding and tension apertures 30 and 3| formed therein. The apertures 3| diler from the aperture 30 in that a channel 32 connects the apertures 3| with the surface 33 of the tension ridge whereas the aperture 30 is closed to the said surface 33. 'I'he closed aperture 30 reduces to a minimum the tendency of the thread to jump from the tension posts when the tension is released, which occurs when the machine stops. The apertures 30 and 3| serve to dene and form the tension posts 34,

35, 3s and 31.

Definition: The term tension posts as used in the specification and claims is to be understood as including the posts I2 (Figures 1 to 4), 34, 35, 36, 31 (Figures 5 and 6), 44, 45, 46, 41 (Figure 7), and their equivalents.

The threadA carrier E differs from the carrier D only in the following particulars:

(l) The tension ridge 40 has a greater number of apertures 3| formed therein.

(2) The tension ridge 40 is longer than the ridge 29 and has outwardly inclined edges 4| instead of the inwardly inclined edges 31 in order to permit the formation ofthe additional apertures 3|. (The tension posts 44, 45, 46 and 41 are the equivalents of the tension posts 34, 35, 3,6 and 31 respectively.)

The thread carriers D and E are inserted into the pocket P so that their respective lower edges 38 and 42 rest upon the floor 22 of said pocket.

As is shown in Figure 6 the carriers D or the carriers C` and E may be placed in the pocket P without the use of the spring 9 or 9a. In such event the weight of the carriers is suicient to keep the carriers in their proper positions in the cups. Since the carriers are rigid andare resting on the floor 22 cf the pocket P neither vibration of the machine nor the downward component of the force due to the tension of the thread T will cause the carriers to sink within the cups as occurs with the felts formerly in` use. Instead, the carriers will always remain in the same position.

Where it is found that the cups are too deep foi` the carriers it is only necessary to raise the floor of the pocket P by placing thereon a wad of paper or other non compressible material.

The plural number of apertures and tension posts enable m-e to vary the path of the thread and therefore its tension. In Figure 5 the lines T3, T4 and T5 denote alternative paths of varyl parting from the spirit of my invention which.

in one of its aspects consists in providing a dry thread guide with a nonyielding smooth thread contacting surfacey and forming and positioning the guide so that it Will not be substantially affected by the vibration of the machine. In'another of its aspects it'consists in providing said novel thread guide with thread tension posts having smooth thread contacting surfaces formed thereon. In another of its aspects it consists in throughA the closed ring stance, vertical-walls may be substituted for the converging Walls of Vboth the pocketl and thread.

carrier shown in Figures l to 7 inclusive. Or, if desired, the members C, D and E may ble-'attached directly to the bar B. I prefer at present to construct the carrier C withthe portions 5, l1, I5, 25 and 4i of unglazed porcelain surmounted by the porcelain portion k5, 21, or Mi having the glazed porcelain thread contacting surface I lor 28, from which extend the glazed porcelain tension posts;

i2, or 34 to 3l, orM to 4l. For the porcelains herein used other materials may bensubstituted. In all such cases it is necessary to use some nonyielding material asa base 'for a thread contacting portion which presents a smooth and comparatively hard surfaceto the thread T and will not materially yabrade the thread or be affected by it.

In addition to the variations in structure herein Y outlined many others will suggest themselves to workers in` the art in the light of my disclosure. For this reason it is my desire that the claims which are hereunto ap-pended for the purpose of defining my invention should be limited only by the prior art.
